The most recent time Arsenal came to the Camp Nou, back in 2011, there was intense drama, loads of it, both on and off the pitch. That helps chart the gulf that has opened between the two clubs since they met in the 2006 Champions League Final.
Since Juliano Belletti's dramatic late goal in Paris, a strike that ensured Arsene Wenger's valiant 10-man effort yielded nothing but praise, Arsenal have won four trophies over nearly 10 long years. Half of those trophies have been Community Shields.
Over the same decade, Barcelona have lifted silverware 22 times, including, crucially, three more Champions Leagues and three World Club Cups.
